SAMUEL JONES, OF JACKSON, OHIO.

REFRIGERATOR.

SEEGIFICATION forming part of Letters Patent No. 718,712, dated January 20, 1903.

Application filed Augiist 22,1902. Serial No. 120,711. (No model.)

Io economy of space and in the consumption of ice and the ease with which the articles may be compactly arranged and are made accessible for removal when required.

In its organization the refrigerator comprises a case, a lining within the case and spaced therefrom and forming a vertical cylindrical chamber, a box arranged within the chamber and adapted to receive the refrigerant, circular shelves attached to the box, and

2o means for rotating the box to bring any portion of the shelves in position opposite the door-opening, so as to facilitate placing articles thereon or removing them therefrom.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and drawings hereto attached.

While the essential and characteristic features of the invention are susceptible of modification, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which- Figure l is a perspective View of a refrigerator embodying the invention, fthe top and front doors being open. Fig. 2 is a vertical central transverse section thereof, the doors being closed. Fig. 3 is a horizontal section.

view of a shelf.

Corresponding and like parts are referred to in the following description and indicated Fig. 5 is a perspective in all the views of the drawings by the same reference characters.

The case or cabinet-work of the refrigerator or safe is indicated at l and may be of any size, design, or construction, according to the The interior of the case is reached by means of a top door 2 and a-front door 3, each fitting their respective openings in such a manner as to preclude the entrance of warm air or the escape of cool air. The interior of the case or cabinet-work is lined, and the walls of the lining are spaced from the corresponding or proximal walls of the case, and this space may be packed or not, as desired and as com mon in refrigerators. The lining forms a vertical chamber 4 of cylindrical form, which is open at its top andV provided in its front side with an opening corresponding with the opening in the front closed by`the door 3. A fiange 5 projects outward from the opening in the front side of the cylindrical chamber 4 and enters the opening in the front side of the case and makes a tight joint therewith, and this flange extends across the space formed between the lining and the case. A glass door 6 is hinged to a side of the flange 5 and is adapted to close the opening from which said ange projects, thereby preventing the escape of cool air when turning the box to bring a particular portion of a shelf or shelves in position to be reached through the door-opening. A tube 7 projects downwardly from the bottom of the chamber 4 and extends through an opening 8 in the bottom of the case and is adapted to receive the, pipe 9 pendent from the box 10. The opening 8 is larger than the tube 7 to admit air into the space formed between the case and chamber 4. A damper-controlled opening ll is provided in the lower portion of the fiange 5 adjacent to the inner side of the glass door 6 Awhen the latter is closed, and by uncovering the opening more or less is permitted to circulate upward close to the inner side of the glass door 6 to prevent sweating thereof, which obstructs the viewing of the interior of the chamber, so that it cannot be readily determined when the desired article or portion of the shelf is in position to be readily reached. The upper end of the cylindrical chamber is closed by a cover l2, which is detachably ftted thereto and provided with a damper-controlled opening 13, through which the air is adapted to escape into theupper portion of the case and pass downward into the spaceformed between the lining and case. When the top door 2 is open, the air escaping through the damper-controlled opening 13 is adapted to have a direct escape.

The box 10 is tall and narrow and may be of any form, and as shown it is of rectangular shape in horizontal section and tapering toward its lower end, being approximately of pyramidal form. The pipe 9 projects centrally from the lowerend or bottom of the box and is designed to carry off the water resulting from the melting of the ice. The pipe 9 in addition to carrying off the water also serves as a vertical journal for the box to rotate about and is mounted in a bearing 14, projected upward from the bottom of the chamber4. Aseriesofshelveslareattached to the box l() and are of circular form, their outer edges being upwardly bent to prevent casual displacementof the articles therefrom. The shelves may be secured to the box in any desired way; butit is preferred to detachably fit them to the box, so as to admit of their removal for cleaning or any other purpose. As shown, tongues 16 are pendent from the edges of the opening formed by the shelves for the reception of the box, and these tongues bear laterally against the sides of the box to brace the shelves and are adapted to spring into depressions 17, so as to support the shelves against the weight that may be imposed thereon. Then it is required to remove the shelves, the tongues 16 are pressed outward from the depression 17 and the shelves are slipped from the box by being moved toward and olf from the smaller end thereof. A guide-ring 18 is fitted within the upper portion of the chamber 4 and receives the upper end of the box l0 and prevents lateral displacement thereof and supplements the bearing 14 in holding the box against lateral movement. The guidering is removably fitted within the upper portion of the chamber 4 and is supported upon stops 19, pressed inward from the sides of said chamber. The box is closed at its upper end by a cover 20. An ice-receptacle 2l is located within the box 10 and conforms approximately to the shape thereof and is readily removable. The bottom of the ice-receptacle is provided with openings for the escape of the water resulting from the melting of the ice, said water passing off through the pipe 9 in the manner stated.

Operating means are provided for rotating the box about a vertical axis and may be of any construction, and, as shown, a shaft 22 is journaled near its outer end in a side of the case and near its inner end in a post 23, projected upward from the bottom of the chamber4. A crank 24 is provided at the outer end of the shaft 22 for imparting rotary movement thereto. A gear-wheel 25 is applied to the inner end of the shaft 22 and is adapted to mesh with a companion gear-wheel 26 at the lower end of the box 10. The gear-wheels 25 and 26 may be of any type and, as illustrated, are of the bevel or miter variety.

The ice may be broken or placed in the receptacle 21 in a solid piece, either prior to placing the receptacle within the box 10 or afterit has been arranged therein. The covers 2O and 12 close, respectively, the box lO and chamber 4, and the opening in the top of the case is closed by the door 2. The articles to be preserved are placed upon the shelves 15, the box 10 being turned to bring successive portions of the shelves in position after the parts opposite the door-opening in the front of the case have been properly filled.

Having thus described the invention, what is claimed as new is- 1. In a refrigerator, a box adapted to receive the refrigerant and mounted to turn about a vertical axis, and shelves fitted to said box and having tongues at the edge of the opening formed therein to bear laterally against the sides of the box and make positive engagement therewith to hold the shelves in place, substantially as set forth.

2. In a refrigerator, the combination of the case, a chamber inclosed thereby, a vertical bearing extended upward from the bottom of the chamber, a box located within said chamber, a pipe pendent from the box and mounted in said bearing, and a guide-ring applied to the upper portion of the chamber and adapted to receive the said box, substantially as specified.

3. In a refrigerator, the combination of a case, a`lining for the case forming a vertical cylindrical chamber, corresponding openings in proximal sides of the chamber and case, a liange surrounding the opening of the chamber and extended therefrom across the space between said chamber and case, a dampercontrolled opening in the bottom portion of said ange, a glass door for closing the opening of the chamber, rotary shelves fitted within the chamber, and a cover for the upper end of said chamber and provided with a damper-controlled opening, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
